Technical Information RIA141 Digital field loop powered display unit with explosion proof enclosure Application Your benefits • • • • • • • • Loop-powered display unit in single compartment housing • 5-digit LC display, character height 20.5 mm (0.8") • Illuminated display, rotatable • Trend bargraph in increments of 10% • Background illumination without additional power supply • Measuring range display from -19999 to 99999 • Digital limit switch • Freely programmable units • 3-key operation • Approvals: ATEX, FM, CSA and NEPSI • 3 cable entries • Configuration with ReadWin® 2000 PC software • Configuration without power supply using setup box Oil & gas Petrochemical industry System and apparatus engineering Outdoor applications Laboratory facilities Process data acquisition and monitoring Optional: stainless steel housing for EEx d application 4 â 0 2 1 TI106R/09/en 51008480 RIA141 Function and system design Measuring principle Example of an application of the field display unit The display unit records an analog measuring signal and shows this on the display with background illumination. The LC display shows the current measured value digitally and as a bargraph with limit value violation signalling. The display unit is looped into the 4 to 20 mA circuit and obtains the required energy from there. Measuring system Microcontroller controlled display unit in single chamber field housing with illuminated LC display. The measuring range, decimal point and offset of the display can be configured comfortably by means of three keys in the device with the housing open or by means of a PC with the ReadWin® 2000 PC software. The background illumination of the display is always activated and does not require additional wiring for the power supply. Input Measured variable Current Measuring range 4 to 20 mA (reverse polarity protection) Input • Line voltage drop < 4 V at 3 - 22 mA • Max. line voltage drop < 6 V at max. short-circuit current 200 mA Output Output Digital limit switch Passive, open collector: Imax = 200 mA Umax= 35 V Ulow/max = < 2 V at 200 mA Max. reaction time to limit value = 250 ms Signal on alarm No measured value visible on the LC display, no background illumination. Transmission behavior The display unit allows the HART® transmission protocol to pass unimpeded. 2 Endress+Hauser RIA141 Power supply Electrical connection Terminal assignment of field display unit Terminal Terminal assignment + Measuring signal (+) 4 to 20 mA Signal input - Measuring signal (-) 4 to 20 mA Signal input 1 Terminal for further instrumentation Support terminal 2 Digital limit switch (collector) Switch output 3 Digital limit switch (emitter) Switch output Supply voltage Supply by means of the 4 to 20 mA current loop.
